There is a new-ish reserve at Vitrezay http://www.en-charente-maritime.com/tourisme/visites/poles-nature/vitrezay, three creeks south of Port Maubert. It consists of several large lakes & as well as nature trails & hides, it also features fishing as an activity to learn about. Maybe Rothes should sign on as an instructor!
I flew back to England from Bordeaux yesterday evening & both Vitrezay & Port Maubert were clearly visible though it was beginning to get dark.
Libellule: According to GE the nearest fix we have for Rothes in 2011 is outside the Vitrezay reserve. But I would assume that a visit there is most likely.
